Why We Recommended It
ISS Detector is currently free, down from its usual $11.99 price point, making it the best time to grab this ultimate satellite tracker. Unlike generic astronomy apps, ISS Detector is laser-focused on helping you spot the International Space Station with the naked eye—no telescope required. It sends you an alarm a few minutes before a pass and checks local weather conditions to ensure a clear sky. Whether you’re a space enthusiast or just curious about seeing the ISS, this app turns a complex calculation into a simple notification. The Premium tier adds Starlink trains, Hubble, radio amateur satellites, and more, but the base app already covers the ISS flawlessly. If you've ever wanted to look up and wave at astronauts, now is the window: grab ISS Detector for iOS before it returns to its full price.

User Reviews
GoSatWatch is still my go-to app for satellite work on iOS devices. Primarily because it allows me to use customized Keplerian data and don’t charge for the ability to do so. Not only is the ham Kep data an extra charge, the feed is riddled with inactive satellites that should be purged from the list so I don’t have to be the one to filter everything out. There’s far better TLE resources available, but ISS Detector does a great job of ensuring you can’t use them. If that one change was made, I’d easily raise my review to at least a 4 star - possibly 5 stars. But as for now, ISS Detector is a secondary resource. I wish I had better things to say. I wish the developer was more open about the data they allowed us to use. I hope the extra money we pay is making them happy. It’s surely not being redirected into enhancing the product or adding new features. Just more of keeping the lights on. Take a look at what others are doing - especially GoSatWatch.

I’ve been using this app for some time and really like it. I bought the amateur radio extension. I use it on a iPhone 12. I do have 2 concerns and would love a response from the development team…1. There isn’t a “refresh” button on the iPhone version or a way to tell when the Kep data was last updated. How do I force an update or tell when it was last updated?2. I’m finding that if I record (write down) satellite pass parameters from this app more than 24 hrs in advance they are grossly in error. For example, if I record the parameters for any satellite that will be passing over 2 days from now then wait 2 days and check ISS Detector again on that same pass, the parameters are all changed, and by a lot. Why can’t the app predict reasonably accurate passes a few days in advance?Great app otherwise! 5 stars.
